Separate bodies or solids

Hello,

I am new to this forum, but I think you can help me.  I am using Gibbscam for programming CNCs and SW for my solid models.  In order to get everything programmed in Gibbs I need several variations of the same model.  Currently I make the changes and save the SW file under a new name.  I end up with multiple SW files for my one Gibbs file.  Is it possible to save different models in SW?  Kind of like layers in Autocad or the body bag in Gibbs?
